Description

Crimping type bearing sealing ring

Technical Field

The utility model relates to a bearing transmission machinery technical field especially relates to a crimping formula bearing seal circle.

Background

The bearing is an important part in the modern mechanical equipment. Its main function is to support the mechanical rotator, reduce the friction coefficient in its motion process and ensure its rotation precision.

The sealing of the bearing can be divided into self-contained sealing and external sealing. The bearing with the seal is a device which is manufactured by the bearing with the sealing performance. Such as bearing with dust cap, sealing ring, etc. The sealing structure occupies small space, is convenient to mount and dismount and has lower manufacturing cost. The existing bearing seal has many defects, such as poor dust resistance, serious abrasion of a seal ring and the like, and the sealing performance is poor.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a crimping formula bearing seal circle to current problem.

The utility model discloses a realize through following technical scheme: the utility model provides a crimping formula bearing seal circle, includes the bearing, the bearing comprises outer lane, inner circle and the roll body, the both sides of rolling the body set up the framed of protection roll body, and the hole lateral wall end symmetry of inner circle sets up the step annular, and the outer curved surface distolateral of outer lane sets up outer ditch ring, and the interior bulge loop of step annular suit sealing washer, outer ditch ring muffjoint sealing washer, the sealed card of well terrace ring of sealing washer is joined in marriage in the clearance between outer lane and inner circle terminal surface.

As a further improvement of the scheme, the sealing ring is of a flange type structure, an inner convex ring matched with the step ring groove is integrally arranged at the inner hole end of one end plane of the sealing ring, an outer convex ring matched with the outer groove ring is integrally arranged at the outer curved surface end of one end plane of the sealing ring, and a middle platform ring matched with the outer ring and the inner ring at intervals is arranged between the outer convex ring and the inner convex ring.

As a further improvement to the scheme, the sealing rings are symmetrically clamped and matched on two end faces of the bearing.

As a further improvement to the above scheme, the sealing rings are of concentric circle structures and share the same axial lead.

As a further improvement to the scheme, a first inclined outer convex body is integrally arranged on the ring wall of the inner convex ring of the sealing ring.

As a further improvement to the scheme, the outer wall of the outer convex ring of the sealing ring is integrally provided with a second inclined outer convex body.

As a further improvement to the scheme, the end faces of the outer ring and the inner ring are both provided with screw holes for fixing screws of the sealing ring.

Compared with the prior art, the utility model has the following advantages: the bearing sealing device has the advantages that the structure is simple, the design is reasonable, the idea is novel and unique, the outer convex ring and the inner convex ring of the sealing ring are respectively matched with the outer groove ring of the outer ring and the step ring groove of the inner ring in a clamping mode, lubricating grease near the sealing ring frame is sealed by the middle step ring, meanwhile, external sewage and dust are prevented from entering, corrosion and corrosion to the bearing can be prevented, the service life of the bearing sealing device is prolonged, and particularly, in the transmission process of the bearing, when the inner ring is used as a support, the outer ring rotates, the first outer convex body of the inner convex ring of the sealing ring is pressed into contact with the screw for fixing and compressing, the sealing performance is enhanced, when the outer ring is used as a support, the inner ring rotates, and the second outer convex ring and the.
